[0035] Reference is made to Figure 1 and Figure 2The first embodiment of this application provides a reusable universal reinforcing bar fixing device for fixing reinforcing bars 9. The reusable universal reinforcing bar fixing device includes a fixing base plate 1, a plurality of fixing plates 7 and a plurality of fixing members 71. The fixing base plate 1 is provided with a positioning elongated hole 3 and a fixing elongated part 4. The fixing elongated part 4 includes a first elongated part and a second elongated part. The positioning elongated hole 3 is located between the first elongated part and the second elongated part. The plurality of fixing plates 7 are all provided on the positioning elongated hole 3, and the fixing plates 7 are movable on the positioning elongated hole 3. The fixing plates 7 are provided with positioning holes 73 corresponding to the positioning elongated hole 3. The two ends of the fixing plates 7 are fixedly connected to the first elongated part and the second elongated part respectively by the plurality of fixing members 71. The reinforcing bar 9 passes through the positioning elongated hole 3 and is fixedly connected to the positioning hole 73.

[0036] The fixing plate 7 can move and displace on the positioning elongated hole 3 of the fixed base plate 1. According to the number of reinforcing bars 9 of the precast column 10, the same number of fixing plates 7 can be placed at the corresponding positions of the positioning elongated hole 3. Then, according to the distribution requirements of the reinforcing bars 9 of the precast column 10, the position of the fixing plate 7 can be moved, and the position of the fixing plate 7 on the fixed base plate 1 can be fixed by the fixing member 71. Then, the reinforcing bars 9 can pass through the positioning hole 73 of the positioning elongated hole 3 for fixing and positioning, and then the precast column 10 can be poured and prepared.

[0037] Both sides of the positioning elongated hole 3 are provided with fixing elongated portions 4, namely the first elongated portion 41 and the second elongated portion 42; the fixing member 71 passes through the fixing hole 72 and the fixing elongated portion 4 and abuts against the fixing base plate 1, thereby fixing the fixing piece 7 at a specific position on the fixing base plate 1 and preventing the fixing piece 7 from shifting. The position of the positioning elongated hole 3 can be adjusted according to the actual position of the dowel bar 9 of the precast column 10, so as to facilitate use. The fixing elongated portion 4 can be a through hole, through which the fixing member 71 can pass to fix the fixing piece 7 to the fixing base plate 1; the fixing elongated portion 4 can also be a slot, through which the fixing member 71 can abut against the fixing piece 7, thereby fixing the fixing piece 7 to the fixing base plate 1.

[0038] The fixing base plate 1 can be an alloy plate or a steel plate. Specifically, it can be a standardized aluminum alloy plate or steel plate. "Standardized" means that corresponding positioning elongated holes 3 are provided during the processing and manufacturing of the aluminum alloy plate or steel plate. The width of the positioning elongated hole 3 is determined according to the maximum diameter of the insert rib 9 of the precast column 10. The width of the positioning elongated hole 3 needs to be greater than the maximum diameter of the insert rib 9 to facilitate the insertion rib 9 to pass through and connect and fix with the fixing piece 7 on the positioning elongated hole 3. Specifically, the width of the positioning elongated hole 3 can be 28mm or 30mm. The fixing base plate 1 can be circular, square, rhomboid, elliptical, etc., preferably square.

[0039] The fixing plate 7 can be made of alloy plate or steel plate. Specifically, a 5-10mm thick standardized aluminum alloy plate or steel plate can be used. This thickness is sufficient to secure the position of the fixing rib 9 without being too heavy, thus reducing costs. The positioning holes 73 on the fixing plate 7 can be set according to the diameter of the fixing rib 9 to ensure good locking and positioning function. The preferred diameter of the positioning holes 73 is 14-28mm. The number and size of the fixing plates 7 can be adjusted and combined according to the actual needs of the fixing ribs 9 of the precast column 10.

[0040] Reference Figure 3 The preparation process of the precast column 10 is as follows: according to the detailed drawing or design requirements of the precast column 10, the position of the fixing piece 7 is located, and then the position of all the reinforcing bars 9 is located using the fixing piece 7. All the fixing pieces 7 are locked to the fixed base plate 1 by the fixing piece 71, and then the precast column 10 is obtained by pouring.

[0041] When installing the transfer layer reinforcing bars 9, first, the fixed base plate 1 is positioned according to the axis. Then, the position of the reinforcing bars 9 is determined according to the positioning holes 73 of the fixing plate 7. The reinforcing bars 9 of the transfer layer are fixed according to the position of the positioning holes 73 by pouring concrete. Then, the fixed base plate 1 is fitted onto the reinforcing bars 9, with the bottom surface of the fixed base plate 1 at the same elevation as the current layer. Finally, the fixing plate 7 is adjusted to be level and locked. The transfer layer reinforcing bars are the reinforcing bars used to connect and transfer between different precast columns.

[0042] When installing the non-transfer floor reinforcing bars 9, after binding the reinforcing bars 9, position the fixing pieces 7 using the same method as described above. Then, position and adjust the position and state of the fixing base plate 1, and place the fixing base plate 1 onto the reinforcing bars 9 of the precast column 10. Use the fixing base plate 1 to adjust the position of the reinforcing bars 9 so that there is no deviation or the deviation is within a reasonable range. Then, lock the fixing base plate 1, the reinforcing bars 9, and the fixing pieces 7. The non-transfer floor reinforcing bars mainly refer to the reinforcing bars in the precast columns according to the design requirements of each floor. At this time, it is not necessary to consider the interconnection with different precast columns; it is only necessary to meet the structural design and load requirements of the floor.

[0043] After the above-mentioned reinforcing bars 9 are installed, they can be transported to the required location and then cast on-site using concrete to obtain precast columns 10 for different floors. During the casting process, necessary corrections are required to prevent misalignment.

[0044] The reusable universal rebar fixing device of this embodiment includes a fixed base plate 1, several fixing plates 7, and several fixing members 71. The fixing plates 7 can move and shift on the positioning elongated holes 3 of the fixed base plate 1. After moving to a specific position, the two ends of the fixing plates 7 are respectively fixed to the corresponding positions on the first elongated part 41 and the second elongated part 42 by the fixing members 71, thereby stably fixing the fixing plates 7 in a specific position and preventing the fixing plates 7 from shifting. The rebar 9 passes through the positioning hole 73 and is fixedly connected to the fixing plates 7, thereby fixing the position of the rebar 9. There can be several fixing plates 7, which can correspond to the precast columns 10 with different numbers and positional distributions of rebar 9, so as to carry out the casting and preparation of the precast columns 10. After use, the fixing members 71 can be loosened to separate the fixed base plate 1, the fixing plates 7 and the rebar 9, so that the reusable universal rebar fixing device can be reused and the cost can be reduced. That is, the reusable universal reinforcing bar fixing device of this embodiment can be used repeatedly to prepare precast columns 10 with different numbers and distributions of reinforcing bars 9, and can be reused to meet the requirements of different precast columns 10.

[0045] Reference Figure 4 In some embodiments, the fixing piece 7 is further provided with a fixing hole 72 corresponding to the fixing member 71. The fixing hole 72 includes a first hole 721 and a second hole 722. The first hole 721 corresponds to the first elongated portion 41, and the second hole 722 corresponds to the second elongated portion 42. One end of the fixing piece 7 is fixedly connected to the first elongated portion 41 through the first hole 721 via the fixing member 71, and the other end of the fixing piece 7 is fixedly connected to the second elongated portion 42 through the second hole 722 via the fixing member 71.

[0046] The fixing hole 72 corresponds to the fixing member 71. The fixing member 71 can be a bolt, preferably with a diameter greater than or equal to 10 mm. Specifically, the diameter can be 10 mm or 12 mm. It can pass through the fixing hole 72 and stably set the fixing piece 7 at a specific position of the first long part 41 and the second long part 42 of the fixing base plate 1.

[0047] The single fixing piece 7 is positioned on the fixing base plate 1 by the first hole 721 and the second hole 722 on both sides of the positioning hole 73 and the corresponding fixing member 71, thereby preventing the fixing piece 7 from shifting.

[0048] The first hole 721 corresponds to the first elongated portion 41, and the second hole 722 corresponds to the second elongated portion 42. That is, the positioning hole 73 is located between the first hole 721 and the second hole 722 and corresponds to the positioning elongated hole 3. The fixing member 71 can pass through the first elongated portion 41 and the first hole 721, thereby fixing one end of the fixing piece 7 to the first elongated portion 41. Then, another fixing member 71 passes through the second elongated portion 42 and the second hole 722, thereby fixing the other end of the fixing piece 7 to the second elongated portion 42, so that the position of the fixing piece 7 is determined and the fixing piece 7 is prevented from shifting.

[0049] Furthermore, the minimum distance between the first hole 721 and the outer edge of the fixing piece 7, and the minimum distance between the second hole 722 and the outer edge of the fixing piece 7 are both greater than or equal to 10mm. This ensures that the fixing piece 7 is not easily damaged or bent during the processing of the fixing hole 72. At the same time, the fixing hole 72 and the fixing member 71 provide sufficient bonding force for the connection between the fixing piece 7 and the fixing base plate 1, preventing the fixing piece 7 from shifting.

[0050] In some embodiments, the distance between the positioning elongated hole 3 and the first elongated portion 41, and the distance between the positioning elongated hole 3 and the second elongated portion 42 are both greater than or equal to 20 mm.

[0051] When the fastener 71 passes through the fixing hole 72 but is not fully locked with the fixing length 4, the fastener 71 can be moved on the fixing length 4 to adjust the position of the fixing piece 7 on the fixing base plate 1, and then the position of the fixing piece 7 can be set according to the position of the insert rib 9, so that the fixing piece 7 can correspond to the insert rib 9 in the future.

[0052] Specifically, the distance between the positioning elongated hole 3 and the first elongated portion 41, and between the positioning elongated hole 3 and the second elongated portion 42, is greater than or equal to 30mm. This facilitates the machining of the positioning elongated hole 3, the first elongated portion 41, and the second elongated portion 42 on the fixed base plate 1, and prevents cracking between the positioning elongated hole 3 and the first elongated portion 41, and between the positioning elongated hole 3 and the second elongated portion 42, which could damage the fixed base plate 1. In addition, the minimum distance between the fixed elongated portion 4 and the outer edge of the fixed base plate 1 is greater than or equal to 50mm, to prevent cracking between the fixed elongated portion 4 and the outer edge of the fixed base plate 1 during the machining of the fixed elongated portion 4, which could damage the fixed base plate 1.

[0053] In some embodiments, the positioning elongated hole 3 includes a first elongated hole 31, a second elongated hole 32, a third elongated hole 33, and a fourth elongated hole 34; the first elongated hole 31 is disposed on the right side of the fixed base plate 1; the third elongated hole 33 is disposed on the left side of the fixed base plate 1 and corresponds to the first elongated hole 31; the second elongated hole 32 is disposed on the upper side of the fixed base plate 1; and the fourth elongated hole 34 is disposed on the lower side of the fixed base plate 1 and corresponds to the second elongated hole 32.

[0054] The positioning elongated holes 3 include a first elongated hole 31, a second elongated hole 32, a third elongated hole 33, and a fourth elongated hole 34 respectively provided on the right, upper, left, and lower sides of the fixing base plate 1, facilitating the fixing of the reinforcing bars 9 in different positions. Specifically, the first elongated hole 31, the second elongated hole 32, the third elongated hole 33, and the fourth elongated hole 34 are provided with corresponding first elongated portions 41 and second elongated portions 42 on both sides, facilitating the fixing of the corresponding fixing pieces 7 to the corresponding positions on the fixing base plate 1, thereby fixing the reinforcing bars 9 in different positions.

[0055] Specifically, there can be several fixing pieces 7, corresponding to the number of inserts 9, which can be respectively set on the first long hole 31, the second long hole 32, the third long hole 33 and the fourth long hole 34, so as to fix the inserts 9 in different positions and in different numbers at the same time, and meet the different preparation requirements of the precast column 10.

[0056] The widths of the first long hole 31, the second long hole 32, the third long hole 33, and the fourth long hole 34 are specifically set according to the maximum diameter of the insertion rod 9, preferably greater than or equal to 30mm, to facilitate the insertion of most insertion rods 9.

[0057] In some embodiments, a pouring hole 2 is provided at the center of the fixed base plate 1. The center point 6 of the pouring hole 2 can coincide with the center point 6 of the fixed base plate 1, allowing the precast column 10 to be poured through the pouring hole 2 after the reinforcing bars 9 are fixed, thereby producing the precast column 10. The shape of the pouring hole 2 is not limited and can be set according to actual needs. It is preferably circular with a diameter greater than or equal to 200 mm to facilitate the pouring of concrete.

[0058] Furthermore, when the first long hole 31, the second long hole 32, the third long hole 33 and the fourth long hole 34 are all fixed with reinforcing bars 9, the fixed base plate 1 can be kept horizontal, so that the concrete poured in through the pouring hole 2 can be poured horizontally to the bottom of the reinforcing bars 9, thereby making the precast column 10 prepared by pouring horizontally.

[0059] In some embodiments, the fixed base plate 1 is further provided with a scale line 11, which is located between the positioning elongated hole 3 and the fixed elongated part 4. The position of the fixing piece 7 can be directly referenced to the scale line 11 for positioning, preventing errors.

[0060] In some embodiments, a horizontal observer 5 is also provided on the fixed base plate 1, and the horizontal observer 5 is located on the side of the fixed elongated part 4 away from the pouring hole 2.

[0061] The horizontal observation device 5 is used to observe the levelness of the fixed base plate 1, so that the height and levelness of the pouring can be determined based on the fixed base plate 1 as a reference, so that the top of the precast column 10 obtained after pouring is level; at the same time, the verticality of the reinforcing bar 9 can also be determined based on the fixed base plate 1.

[0062] There can be several horizontal observation devices 5, specifically four, which are respectively set in the four directions of the fixed base plate 1 (up, down, left, right) and located on the side of the fixed long part 4 away from the pouring hole 2. They can detect the levelness of the fixed base plate 1 from four directions, preventing deviations in the verticality of the reinforcing bars 9 and unevenness at the top of the precast column 10, which would increase the difficulty of construction and affect the stability and quality of the precast column 10 structure.

[0063] In some embodiments, a center point 6 is also provided on the fixed base plate 1, and the center point 6 is located on the side of the horizontal observer 5 opposite to the pouring hole 2. Specifically, the number of center points 6 corresponds one-to-one with the number of horizontal observers 5. The center line of the center point 6 is used as a reference to perform planar positioning and calibration of the reinforcing bar 9. The combination of the center point 6 and the horizontal observer 5 can simultaneously achieve dual calibration of position and status, thereby fixing the position of the reinforcing bar 9 according to the design requirements and preventing structural and positional deviations in the precast column 10.

[0064] In some embodiments, a viewing line 8 is also provided on the fixed base plate 1, and the viewing line 8 is fitted and connected to the fixed long part 4.

[0065] The purpose of the guide line 8 is as a reference. When fixing the reinforcing bars 9, the position can be marked by the guide line 8, thereby reducing errors caused by the displacement of the reinforcing bars 9 during pouring. Specifically, the guide line 8 is located on the fixing length 4. By determining the position of the fixing member 71, the position of the fixing piece 7 is located, and thus the position of the reinforcing bar 9 is fixed. The guide line 8 can be marked with chalk or other colored pens and can be replaced after one use. Specifically, at least one guide line 8 is provided on the fixing length 4 of the first long hole 31, the second long hole 32, the third long hole 33, and the fourth long hole 34 to facilitate the fixing of different numbers of reinforcing bars 9.

[0066] The line 8, center point 6, and horizontal observation device 5 are used in combination to locate the position of the reinforcing bar 9, preventing structural and positional differences in the precast column 10. Simultaneously, the position of the reinforcing bar 9 can be observed and adjusted in a timely manner during the pouring process to prevent misalignment of the precast column 10.

[0067] The fixing piece 7 can be a pair of alloy pieces with identical structure and shape. One is set above the fixing base plate 1, and the other is set below the fixing base plate 1. The fixing member 71 passes through the fixing hole 72 of the upper alloy piece, the fixing elongation 4 of the fixing base plate 1, and the fixing hole 72 of the lower piece in sequence to fix the position of the alloy piece. Similarly, the fixing member 71 can also fix the position of the alloy piece by passing through the fixing hole 72 and the fixing elongation 4 in the opposite direction.

[0068] The position of the insert 9 is fixed by passing it through the positioning hole 73 of the lower alloy sheet, the positioning elongated hole 3 of the fixing base plate 1 and the positioning hole 73 of the upper alloy sheet in sequence; the position of the insert 9 can also be fixed by passing it through the positioning hole 73 and the positioning elongated hole 3 in the opposite direction.

[0069] The arrangement of a pair of alloy plates allows the fixing base plate 1 to be sandwiched between the alloy plates, thereby improving the connection stability between the alloy plates and the fixing base plate 1 and preventing the insertion rod 9 from shifting.

[0070] The surface of the fixing plate 7 near the fixing base plate 1 is rough, and several protrusions are provided on the rough surface, which can increase the bonding force between the fixing plate 7 and the fixing base plate 1, thereby improving the connection stability between the fixing plate 7 and the fixing base plate 1. When the insert 9 is positioned and fixed by the fixing plate 7, the strong bonding force between the fixing plate 7 and the fixing base plate 1 can improve the stability of the position of the insert 9 and prevent the insert 9 from shifting.

[0071] Reference Figure 5 In some embodiments, the outer edge of the positioning elongated hole 3 of the fixing piece 7 extends along the direction close to the fixing base plate 1 and is provided with a first abutting protrusion 731. The spacing of the outer edges of the first abutting protrusion 731 is equivalent to the width of the positioning elongated hole 3. The first abutting protrusion 731 can be embedded into the positioning elongated hole 3 to perform the initial positioning of the fixing piece 7. Then, by sliding the first abutting protrusion 731 in the positioning elongated hole 3, the specific position of the fixing piece 7 is positioned, which can prevent the fixing piece 7 from falling off or being lost during operation.

[0072] Furthermore, a second abutting protrusion 7211 is provided on the outer edge of the first long portion 41 extending in the direction close to the fixed base plate 1. The spacing between the outer edges of the second abutting protrusion 7211 is equivalent to the width of the first long portion 41. The second abutting protrusion 7211 can be embedded into the first long portion 41 to perform the initial positioning of the fixing piece 7. Then, by sliding the second abutting protrusion 7211 in the first long portion 41, the specific position of the fixing piece 7 can be positioned, which can prevent the fixing piece 7 from falling off or being lost during operation.

[0073] Similarly, a third abutting protrusion 7221 is provided on the outer edge of the second elongated portion 42 extending in the direction close to the fixed base plate 1. The spacing between the outer edges of the third abutting protrusion 7221 is approximately equal to the width of the second elongated portion 42. The third abutting protrusion 7221 can be embedded into the second elongated portion 42 to initially position the fixing piece 7. Then, by sliding the third abutting protrusion 7221 within the second elongated portion 42, the specific position of the fixing piece 7 is determined, preventing the fixing piece 7 from falling off or being lost during operation. Specifically, the shapes of the first abutting protrusion 731, the second abutting protrusion 7211, and the third abutting protrusion 7221 can be the same or different, but preferably they are all the same to facilitate processing and manufacturing.

[0074] In summary, this application provides a reusable universal rebar fixing device, including a fixed base plate, several fixing plates, and several fixing components. The fixing plates can move and shift on the positioning elongated holes of the fixed base plate. After moving to a specific position, the fixing components fix the two ends of the fixing plates to the corresponding positions of the first and second elongated parts, respectively, thereby stably fixing the fixing plates at that specific position and preventing the fixing plates from shifting. The rebar passes through the positioning holes and is fixedly connected to the fixing plates, thereby fixing the position of the rebar. There can be several fixing plates, which can correspond to precast columns with different numbers and positional distributions of rebars, thereby enabling the casting and preparation of precast columns. After use, the fixing components can be loosened to separate the fixed base plate, fixing plates, and rebars, thereby allowing the reusable universal rebar fixing device to be reused and reducing costs.
